<p>A liquid-filled device including a pair of superimposed pliable sheets that are interconnected or sealed along peripheral edges. The superimposed pliable sheets are also interconnected along an inner seam. A first chamber for containing a liquid is defined by a space between peripheral edges of the sheets and the inner seam. The portion of the device which is between the superimposed pliable sheets and which is inboard of the inner seam defines a second chamber for containing a liquid. The device further includes an opening along a portion of the inner seam, which opening is sufficiently large to permit both liquid and discrete articles within that liquid to flow in both directions between the first and second chambers.</p> |
